ansible-playbook command prompt like yes/no while connecting to managed node for the first time

Hello, All
My ansible-playbook -i -vv command prompt like yes/no while connecting to managed node for the first time. How can i avoid the prompting because i have aggregated all ansible-playbook commands in a shell script and running the shell script from UI.

And playbook command prompt like yes/no while connecting to managed node for the first time, how can i avoid this.

thanks

In ansible.cfg try setting host_key_checking = false
